2-Bromo-2-Nitro-1, 3-Propanediol (Bronopol)

CAS No.: 52-51-7 Molecular Formula: C3H6BrNO4

Molecular Weight: 199.99

Structural Formula:

Property:

Appearance - 2-Bromo-2-Nitro-1, 3-Propanediol (Bronopol) is supplied as crystals or crystalline powder, which may vary from white to pale yellow in colour depending on the grade of material being offered.

Melting Point - As a pure material, Bronopol has a melting point of about 130º C. However due to its polymorphic characteristics, Bronopol undergoes a lattice rearrangement at 100 to 105º C and this can often be wrongly interpreted as the melting point.

Solubility - 2-Bromo-2-Nitro-1, 3-Propanediol (Bronopol) is readily soluble in water although the dissolution process is endothermic. Solutions containing up to 28% w/v are possible at ambient temperature.

2-Bromo-2-Nitro-1, 3-Propanediol (Bronopol) is poorly soluble in non-polar solvents but shows a high affinity for polar organic solvents.
